Engineers hand 'cognitive' control to underwater robots

ven, 08/05/2015 - 10:58
For the last decade, scientists have deployed increasingly capable underwater robots to map and monitor pockets of the ocean to track the health of fisheries, and survey marine habitats and species. In general, such robots are effective at carrying out low-level tasks, specifically assigned to them by human engineers -- a tedious and time-consuming process for the engineers. Now a new programming approach gives robots more "cognitive" capabilities, enabling humans to specify high-level goals, while a robot performs high-level decision-making to figure out how to achieve these goals.

Researchers hack a teleoperated surgical robot to reveal security flaws

jeu, 07/05/2015 - 14:53
How safe is that robot doing your surgery? Researchers easily hacked a next generation teleoperated surgical robot to test how easily a malicious attack could hijack remotely-controlled operations in the future and to offer security solutions.

Soft robot: Shaping itself and moving with own internally generated power?

What if a new material would allow for development of a 'soft robot' that could reconfigure its own shape and move using its own internally generated power?

Combining computer vision, brain computer interface for faster mine detection

lun, 04/05/2015 - 14:18
Computer scientists have combined sophisticated computer vision algorithms and a brain-computer interface to find mines in sonar images of the ocean floor. The study shows that the new method speeds detection up considerably, when compared to existing methods -- mainly visual inspection by a mine detection expert.

Human-inspired robot takes a brisk walk in the grass

dim, 03/05/2015 - 10:16
In a rolling, outdoor field, full of lumps, bumps and uneven terrain, researchers have successfully field-tested for the first time the locomotion abilities of a two-legged robot with technology that they believe heralds the running robots of the future.

Making robots more human: Wearable sensors read human facial expressions

mer, 29/04/2015 - 10:10
Most people are naturally adept at reading facial expressions -- from smiling and frowning to brow-furrowing and eye-rolling -- to tell what others are feeling. Now scientists have developed ultra-sensitive, wearable sensors that can do the same thing. Their technology could help robot developers make their machines more human.

Human brain inspires computer memory

mar, 28/04/2015 - 08:17
How is it possible to create computer memory that is both faster and consumes less energy? Researchers have unlocked the physical mechanisms involved in new-generation magnetic memory, and have shown that these mechanisms could be used as "synapses" in a new type of neuro-inspired system, able to learn how to store and retrieve information.

Making biotechnology interactive with games, remote-control labs

mar, 21/04/2015 - 08:48
What if you could interact with cells like fish in an aquarium? Build your own micro-aquarium for cells? Even perform remote-control experiments in robotic biolabs in the cloud? A research team shows how.

Artificial intelligence system created to provide therapy for people who have suffered a cerebral stroke

mar, 21/04/2015 - 08:43
Artificial intelligence, virtual worlds and interaction with video games, are the elements of a new therapy designed to help people who have had a stroke and children with cerebral palsy to recover mobility of their upper extremities quickly.

Graphics in reverse: Probabilistic programming does in 50 lines of code what used to take thousands

lun, 13/04/2015 - 11:06
Researchers can demonstrate that on some standard computer-vision tasks, short programs -- less than 50 lines long -- written in a probabilistic programming language are competitive with conventional systems with thousands of lines of code.

Improving the quality of medical care using computer understanding of human language

jeu, 09/04/2015 - 12:03
How can computer-based analysis of free text -- the narrative comments found in medical records and expressed in everyday language or technical terminology - help improve the quality of medical care?

Gotcha! Ultra-realistic robot proves there's more than one way to scare a fish

mar, 07/04/2015 - 08:53
In a side-by-side comparison, a robotic predator can frighten zebrafish just as well as the real thing, a new experiment demonstrates. These results may help advance understanding of fear and anxiety in animal populations, including humans. Zebrafish are increasingly taking the place of more complex animals in behavioral studies. Experiments have shown the advantages of using robots in studies of fish behavior, including repeatability and consistency.

HIV spreads like internet malware and should be treated earlier

jeu, 02/04/2015 - 16:17
A new model for HIV progression finds that it spreads in a similar way to some computer worms and predicts that early treatment is key to staving off AIDS. HIV specialists and network security experts noticed that the spread of HIV through the body using two methods -- via the bloodstream and directly between cells -- was similar to how some computer worms spread through both the internet and local networks respectively to infect as many computers as possible.

A robot prepared for self-awareness: Expanded software architecture for walking robot Hector

mar, 31/03/2015 - 11:34
A year ago, researchers showed that their software endowed the walking robot Hector with a simple form of consciousness. Their new research goes one step further: they have now developed a software architecture that could enable Hector to see himself as others see him. "With this, he would have reflexive consciousness," explains an expert. The architecture is based on artificial neural networks.

Intelligent neuroprostheses mimic natural motor control

lun, 30/03/2015 - 21:43
Neuroscientists are taking inspiration from natural motor control to design new prosthetic devices that can better replace limb function. Researchers have tested a range of brain-controlled devices -- from wheelchairs to robots to advanced limbs -- that work with their users to intelligently perform tasks.

Designer's toolkit for dynamic DNA nanomachines: Arm-waving nanorobot signals new flexibility in DNA origami

jeu, 26/03/2015 - 15:16
Researchers have demonstrated a new approach to joining -- and reconfiguring -- modular DNA building units, by snapping together complementary shapes instead of zipping together strings of base pairs. This not only opens the way for practical nanomachines with moving parts, but also offers a toolkit that makes it easier to program their self-assembly.

Pioneering techniques in computer vision and robotics pave the way for future underwater surveying in Cardigan Bay

Artificial hand able to respond sensitively thanks to muscles made from smart metal wires

mar, 24/03/2015 - 08:47
Engineers have taken a leaf out of nature's book by equipping an artificial hand with muscles made from shape-memory wire. The new technology enables the fabrication of flexible and lightweight robot hands for industrial applications and novel prosthetic devices. The muscle fibers are composed of bundles of ultrafine nickel-titanium alloy wires that are able to tense and flex. The material itself has sensory properties allowing the artificial hand to perform extremely precise movements.

Snake robots learn to turn by following the lead of real sidewinders
